Letters Patent No. 102,851, dated May 10, 1870.

IMPROVEMENT IN MECHANISMl FIOR STRIPPING THE TOP FLATS OF CARDING--MA- CHINES.

l The Scheule referred to in these Letters Patent and making part of Ythe same To all whom it may concern Be it known that I, FERDINANDMORE, of Wetzifull, clear, and exact description thereof, which willl enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specificationv This invent-ion is applicable to the machines known as George 'Vellmans patent self-stripping cardingengines, and forwhich Letters Patent were granted in the United Kingdom of Great Britain to the said George Wellman, on the 11th day of September, 1860, N o. 2,190.

The object of the present invention is to enable the top flats or top cards to be stripped in any required succession, instead ofstripping them in regular alternate succession, as described in the specication' of the-said George Wellman; and, in order-that the invention may be fully understood, I will proceed to describe it, with the aidof the accompanying sheets of` drawings, referencebeinghadto the ligures and letters marked thereon.

Figure 1 is a side elevation of a raiding-engine, with my improvements. n

Figure 2 is a plan or top view of the same.

Figure 3 is an inner face view of the principal gearwheel.v

Figure 4 is a vertical transverse section of the machine. l

Similar letters of reference indicate corresponding parts. y y

a is the main frame, which is to contain the main cylinder and the doffer of the carding-machine.

c are the mangle segments iixed to the sides ot' the. frame.

d are the rocker-trames, supported in the projecting ends of the axle b of the main cylinder.

To these rocker-frames are attached the stripping apparatus of the top cards e. I have in this instance represented twenty top cards, but the number may be increased orvdiminislied.

The rocker-frames d, and the parts connected therewith, are counterbalanced bythe weights f, which are jointed, as usual, to the lower arms of the rockerframes.

g is the principal wheel of the strip ing apparatus; It is loose on the stud h, which is fixer on the rockerframe d.

'i is the shaft, with the small rack-pinion i', which gears in the mangle'segment c, xed to the bend of the carding-engine, and which sets the stripping apparatus in motion.

This pinion may be assisted'in traveling over the.

lcenters of the yrnangle segments by a spring (not shownl in the drawing) fixed to the rocker-frame d, and pressing against ,the double arl'n or frame d', in'wlnch the shaft Ii revolves. The stud h connect-s this arm el to v the teeth g1 are narrow, and' equidist-ant from the inf ner and outer face.

One-halt' of the remaining third has teethnq2 extending from face to face of the wheel, and the remaining teeth, g3, reach from the outer face of' g to the inner end ot' the teeth g1.

To the pinion j is fixed the tumbler-plate j.

lm is a worm fixed on the boss of the wheel g. l

This worm gears into the worm-wheel u, which rcvolves on a stud, o, that is xcd in a projection of the arm d."

1) is an eccentric tixed on the worm-wheel a, and

q is a catch-lever on a stud, Z, which is also iixed on the arm d. This catch-lever q is acted upon by the eccentric p, and acts on the sliding pinions on the shaft i.

tis a second pinion on the shaft i. It is similar to the pinion j, and is firmly connected with the same, by means ot' a sleevekencircling and turning loosely on the shaft i, so that both will slide and rerolve on said shaft simultaneously. The lever q, through the mction given to it hy the eccentric 1, causes the pinion t.

toislide on the shaft i, and brings it into or out ot' gear with the toothed segments q2 gi.

A spring, u, throws the wheels j t outward, and holds Ithe catelilever against the eccentric. y

The shaft t' makes thus two revolutions,instead of only one, as usual. 1t is driven once'a-round by the broad-toothed segment g2 of the wheel g and the pin- .y ion j, as usual, and is driven around a second time by Y the segment y, on`thc outside of 'the `wheel g, gear-` ing into the pinion t, so that, when both segments are in gear with the pinions, the whole ,apparatus travels double the usual distance, and goes over three top cards, instead of only one. v

It is evident that the eccentric p must be made so that the pinion t is thrown ont of gear .during the stripping of the iirst half of the top cards, in order that the stripping appara-tus may travel only its usual.v

distance, and that it must come into operation duringthe stripping of the second half of the top cards, when the apparatus travels a double distance.

The stripping apparatus consists of ra plate, c, secured to arms w that are pivoted` to the .frame d, and that have projecting pins4 :n fitting into grooves a.' of

,he wheels y, said grooves giving to the stripper the `eqnired motion.

The top cards are lifted by slides s, which are also worked by grooves y of the wheels y.

The inode of operation is as follows:

\Vhen the stripping apparatus, start-ing from the feeding end of the machine, has stripped the first, third, fifth, and seventh cards, and arrives at the ninth top card, and has stripped it also, the pinion f comes into gear with the segmentg, and the apparatus then moves at the next motion to the thirteenth top card, and strips it, and then the seventeeth. Returning, the twentieth, sixteenth, and twelfth top cards are stripped; when thc pinion t is drawn out of gear, and the apparatus strips the top cardsfmarked 10, 8, G, 4, 2. Returning again, the first, third, fth, scventh, ninth, and eleventh top cards are' stripped. At this point the pinion t comes again into gear, and the apparatus now strips the top cards marked 15 and 19, and returning again strips those marked 1S, 14, and 10, when the pinion t is again thrown out of gear, and the amraratns strips the top cards marked 8, (i, 4, and 2, which brings it again to the position from which it started, and the above-described operation commences again,

The first ten top cards areI conseqnenti)4 stripped naam twice while the last ten are only strippedonce; in all, thirty top cards are stripped, so that the wheel y has to make thirty revolutions while the worm-wheel n and the eccentric p make one revolution.

The tumblcr-plates of the pinions tit into gaps or recesses of the wheel g, as long as such pinions are revolved. At other times these plates are guided hy flanges of the wheel g.

By varying the number of teeth in the wheels, segments, and pinions, and the shape of the eccentric, the order of the succession in which the top Hats are stripped may be modified or varied.

Having thus described my invention, i

I claim as new and desire to secure by Letters Patentv 1. The combination ofthe wheel g, having teeth of different widths', as specified, and the sliding pinions j t, all arranged and operating as set forth, for the purpose indicated.

, 2. The combination of the cani 1) and clutch-lever q with the sliding wheels t j and wheels g, all arranged to operate substantially as herein shown and described. i
